1266102-44-6 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 1266102-44-6 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,6,6,1,0 and 2 respectively; the second part has 2 digits, 4 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1266102-44:
(9*1)+(8*2)+(7*6)+(6*6)+(5*1)+(4*0)+(3*2)+(2*4)+(1*4)=126
126 % 10 = 6
So 1266102-44-6 is a valid CAS Registry Number.

Synthesis of the antiproliferative agent hippuristanol and its analogues via Suárez cyclizations and Hg(II)-catalyzed spiroketalizations

Ravindar, Kontham,Reddy, Maddi Sridhar,Lindqvist, Lisa,Pelletier, Jerry,Deslongchamps, Pierre

, p. 1269 - 1284 (2011/04/26)

A full account of the synthesis of hippuristanol and its analogues is described. Hecogenin acetate was identified as a suitable and economical starting material for this work, and substrate-controlled stereoselection was obtained throughout the construction of the key spiroketal unit. Suárez cyclization was first used, but Hg(II)-catalyzed spiroketalization of the 3-alkyne-1,7-diol motif was finally identified as the most convenient strategy.(Figure Presented)
